An assessment of phase field fracture: crack initiation and growth

Submitted by Emilio Martíne… on

Dear iMechanicians,

We have contributed to the Special Issue organised by the Royal Society on occasion of the centenary of Griffith's seminal paper with a paper revisiting phase field fracture methods and their connection with conventional fracture mechanics theory. I hope that you find it of interest. (https://royalsocietypublishing.org/doi/10.1098/rsta.2021.0021)

Computing wrinkling and restabilization of stretched sheets based on a consistent finite-strain plate theory

Submitted by Fan Xu on

It was reported both in experiments and computations using some classical plate theories that wrinkles can appear in a uniaxially stretched rectangular hyperelastic film with clamped-clamped boundaries and can be suppressed upon further tension. Here, based on a recently-available consistent finite-strain plate theory, we investigate this complex instability problem with isola-center bifurcation (the nontrivial solution curve begins and ends at two distinct points on the trivial line) in more depth and present an efficient numerical algorithm.

Effects of Cleavage Plane and Material Strength on Fracture of Polycrystalline Brittle Materials: A Phase-Field Modeling Study

Submitted by mohsenzaeem on

A modified phase-field model for fracture is presented which includes the material strength and cleavage planes to quantitatively predict the crack propagation path and the mechanical response in polycrystalline brittle materials. Computational Materials Science 197 (2021) 110642 (11 pages).
